More clear application solution drawings and kits should be available to realize possibilities for utilizing those in practice. For example existing IHF output is driving low current ext DC boosted amplifier input: loss of money and space; thus I2S or relevant audio signal possibilities must be taken into account in amp chip and engine side.

Make sure to select an amplifier IC that not only matches your power supply voltage range, also make sure to fine the one that has an application circuit that is within your skill level.
~Kyle F, Design Engineer, Danbury, CT
Use highest quality parts possible (within reason) in the signal path. STUDY, STUDY, STUDY. Every time I find a new chip amp web-site, I learn something new.
~Dave N, Purchaser, Louisville, KY
If they used audio amplifier chips they can save money because chips are cheap to buy and easy to assemble with only few external components.
~Ranulfo Y, Technical Support, Cebu city, Philippines
Be careful because there are a lot of piracy chips.
~Fabio Alarcon, Production Engineer, Bogota, Colombia
Look at the specs, then the price.
~Erik M, Research & Development, Ljubljana, Slovenia
Always read the datasheet first.
~Kamarul Azman K, Research & Development, Ipoh, Malaysia
Use real digital inputs.
~Engineering, Design, Pierrelatte, France
Care when paralleling.
~Joachim G, Design Engineer, Brilon, Germany
Research the market.
~Pieter S, Retired engineer, Johannesburg, South Africa
Depend on the design, don't have specific advice.
